While very useful, XHR is not a very - nice API. It suffers from lack of separation of concerns. The input, output - and state are all managed by interacting with one object, and state is - tracked using events. Also, the event-based model doesn’t play well with - JavaScript’s recent focus on Promise- and generator-based asynchronous - programming.</p> - <p>The <a href="https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API">Fetch API</a> intends - to fix most of these problems. It does this by introducing the same primitives - to JS that are used in the HTTP protocol. In addition, it introduces a - utility function <code>fetch()</code> that succinctly captures the intention - of retrieving a resource from the network.</p> - <p>The <a href="https://fetch.spec.whatwg.org">Fetch specification</a>, which - defines the API, nails down the semantics of a user agent fetching a resource. - This, combined with ServiceWorkers, is an attempt to:</p> - <ol> - <li>Improve the offline experience.</li> - <li>Expose the building blocks of the Web to the platform as part of the - <a - href="https://extensiblewebmanifesto.org/">extensible web movement</a>.</li> - </ol> - <p>As of this writing, the Fetch API is available in Firefox 39 (currently - Nightly) and Chrome 42 (currently dev). Github has a <a href="https://github.com/github/fetch">Fetch polyfill</a>.</p> - -<h2>Feature detection</h2> - - <p>Fetch API support can be detected by checking for <code>Headers</code>,<code>Request</code>, <code>Response</code> or <code>fetch</code> on - the <code>window</code> or <code>worker</code> scope.</p> - -<h2>Simple fetching</h2> - - <p>The most useful, high-level part of the Fetch API is the <code>fetch()</code> function. - In its simplest form it takes a URL and returns a promise that resolves - to the response. The response is captured as a <code>Response</code> object.</p> - <div - class="wp_syntax"> - <table> - <tbody> - <tr> - <td class="code"><pre class="javascript" style="font-family:monospace;">fetch<span style="color: #009900;">(</span><span style="color: #3366CC;">"/data.json"</span><span style="color: #009900;">)</span>.<span style="color: #660066;">then</span><span style="color: #009900;">(</span><span style="color: #000066; font-weight: bold;">function</span><span style="color: #009900;">(</span>res<span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - <span style="color: #006600; font-style: italic;">// res instanceof Response == true.</span> - <span style="color: #000066; font-weight: bold;">if</span> <span style="color: #009900;">(</span>res.<span style="color: #660066;">ok</span><span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - res.<span style="color: #660066;">json</span><span style="color: #009900;">(</span><span style="color: #009900;">)</span>.<span style="color: #660066;">then</span><span style="color: #009900;">(</span><span style="color: #000066; font-weight: bold;">function</span><span style="color: #009900;">(</span>data<span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - console.<span style="color: #660066;">log</span><span style="color: #009900;">(</span>data.<span style="color: #660066;">entries</span><span style="color: #009900;">)</span><span style="color: #339933;">;</span> - <span style="color: #009900;">}</span><span style="color: #009900;">)</span><span style="color: #339933;">;</span> - <span style="color: #009900;">}</span> <span style="color: #000066; font-weight: bold;">else</span> <span style="color: #009900;">{</span> - console.<span style="color: #660066;">log</span><span style="color: #009900;">(</span><span style="color: #3366CC;">"Looks like the response wasn't perfect, got status"</span><span style="color: #339933;">,</span> res.<span style="color: #660066;">status</span><span style="color: #009900;">)</span><span style="color: #339933;">;</span> - <span style="color: #009900;">}</span> -<span style="color: #009900;">}</span><span style="color: #339933;">,</span> <span style="color: #000066; font-weight: bold;">function</span><span style="color: #009900;">(</span>e<span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - console.<span style="color: #660066;">log</span><span style="color: #009900;">(</span><span style="color: #3366CC;">"Fetch failed!"</span><span style="color: #339933;">,</span> e<span style="color: #009900;">)</span><span style="color: #339933;">;</span> -<span style="color: #009900;">}</span><span style="color: #009900;">)</span><span style="color: #339933;">;</span></pre> - </td> - </tr> - </tbody> - </table> - </div> - <p>Submitting some parameters, it would look like this:</p> - <div class="wp_syntax"> - <table> - <tbody> - <tr> - <td class="code"><pre class="javascript" style="font-family:monospace;">fetch<span style="color: #009900;">(</span><span style="color: #3366CC;">"http://www.example.org/submit.php"</span><span style="color: #339933;">,</span> <span style="color: #009900;">{</span> - method<span style="color: #339933;">:</span> <span style="color: #3366CC;">"POST"</span><span style="color: #339933;">,</span> - headers<span style="color: #339933;">:</span> <span style="color: #009900;">{</span> - <span style="color: #3366CC;">"Content-Type"</span><span style="color: #339933;">:</span> <span style="color: #3366CC;">"application/x-www-form-urlencoded"</span> - <span style="color: #009900;">}</span><span style="color: #339933;">,</span> - body<span style="color: #339933;">:</span> <span style="color: #3366CC;">"firstName=Nikhil&favColor=blue&password=easytoguess"</span> -<span style="color: #009900;">}</span><span style="color: #009900;">)</span>.<span style="color: #660066;">then</span><span style="color: #009900;">(</span><span style="color: #000066; font-weight: bold;">function</span><span style="color: #009900;">(</span>res<span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - <span style="color: #000066; font-weight: bold;">if</span> <span style="color: #009900;">(</span>res.<span style="color: #660066;">ok</span><span style="color: #009900;">)</span> <span style="color: #009900;">{</span> - alert<span style="color: #009900;">(</span><span style="color: #3366CC;">"Perfect!

This is not exposed to the Web, but - it affects which mutation operations are allowed on the Headers object. - <br/>Possible values are:</p> - <ul> - <li>“none”: default.</li> - <li>“request”: guard for a Headers object obtained from a Request (<code>Request.headers</code>).</li> - <li>“request-no-cors”: guard for a Headers object obtained from a Request - created - <br/>with mode “no-cors”.</li> - <li>“response”: naturally, for Headers obtained from Response (<code>Response.headers</code>).</li> - <li>“immutable”: Mostly used for ServiceWorkers, renders a Headers object - <br/>read-only.</li> - </ul> - <p>The details of how each guard affects the behaviors of the Headers object - are - <br/>in the <a href="https://fetch.spec.whatwg.org">specification</a>. For example, - you may not append or set a “request” guarded Headers’ “Content-Length” - header. Similarly, inserting “Set-Cookie” into a Response header is not - allowed so that ServiceWorkers may not set cookies via synthesized Responses.</p> - <p>All of the Headers methods throw TypeError if <code>name</code> is not a - <a - href="https://fetch.spec.whatwg.org/#concept-header-name">valid HTTP Header name</a>.
